Any intelligent fool can make things bigger, more complex, and more violent.

Normally, I would wrap these parameters in quotes, but for some reason, this doesn't work. Process Class In Java If the argument is already a localized stream, it may be returned as the result. And applets run in the sandbox, so they aren't permitted to all the useful things, we normally want to do: write to disk, delete files, open connections to here and there, Returns:A new Process object for managing the subprocess Throws: SecurityException - If a security manager exists and its checkExec method doesn't allow creation of the subprocess

Here is a small example(Exception handling omitted): Process p=Runtime.getRuntime().exec("cmd.exe /c ping 127.0.0.1 -n 10"); System.out.println("Here 1");//this will execute immediately try { p.waitFor(); System.out.println("Here 2");//this will only be seen after +- 10 his comment is here I tried to modify your first example to run telnet, but nothing happened.

You probably don't have the question anymore but other people might so I thought I might answer it. –735Tesla Jan 25 '15 at 22:05 add a comment| up vote 30 down How To Use Runtime.exec In Java Maybe post some code. You can also open up the process' output and error streams.

Enable or disable finalization on exit; doing so specifies that the finalizers of all objects that have finalizers that have not yet been automatically invoked are to be run before the

Once the shutdown sequence has begun it is impossible to register a new shutdown hook or de-register a previously-registered hook. That makes sense, since javac expects us to follow the program with the source code file to compile.Thus, to circumvent the second pitfall -- hanging forever in Runtime.exec() -- if the void halt(intstatus) Forcibly terminates the currently running Java virtual machine.
